"Aah! Haaa! D, darling! That feels so good!"
Elt pressed his body against the backs of her thighs and wrapped his arms around her back. Her legs rested on his shoulders, creating an indecent spectacle. Her knees were forced back nearly to her own chest. She experienced the feeling of being made into a tool for sex.
He pistoned his hips up and down, roughly pushing through the flesh of her passage and slamming his head into her cervix with each downward thrust.
"Aah. My husband's using me as a tool! Making me his plaything!"
All he was doing was thrusting his hips, but Koyoi's mind was full of bliss. She was being useful to someone — to her husband, who was right in front of her. That fact kindled warmth in Koyoi's heart.
"Haa, haa. Yes. Koyoi... you feel... great!"
"Thank you very much! You feel, wonderful too, darling!"
The sound of flesh slapping against flesh filled the air. It was accompanied by the pair's labored breathing, and the sounds of the surrounding monster girls gasping and rubbing their crotches.
"K, Koyoi, I'm cumming."
Inside Koyoi, his glans swelled. Its raised corona rubbed her pleats even more intensely than before.
"Haaa. You're going... to cum... darling?"
Elt gave several flustered little nods. The movements of his hips changed from large thrusts designed to savor the full length of her vagina to shallow twitches meant to strike and rub the entrance to her womb.
"Oooooh! Cumming!"
Elt squeezed Koyoi tight. His hips thrust even further forward, his swollen glans forcing her cervix slightly open. His urethra was connected directly to her womb. Out of it burst a flood of semen — an order of magnitude more voluminous than after her blowjob — with enough force to reach the inner walls of her uterus.
"Aaaah! Ooh! Darling!"
The direct stimulation to her womb was more than enough to send Koyoi to heaven. Her whole sex clamped down tight, aiding the force of the ejaculation.
Ten seconds passed, then twenty, then thirty.
Spasming and panting, Koyoi's climax continued along with Elt's ejaculation.
Forty seconds. Fifty. Sixty Nine.....
Elt gritted his teeth. An incubus' ejaculation went on for a long time. The pleasure of climax remained in his brain for the entire duration.
A minute passed, then two. By the time the pair's bodies relaxed, three minutes had gone by.
Limp and panting, their sexes still joined and bellies pressed together, they gently embraced each other.
"Koyoi," Elt whispered, pressing his cheek against hers. "I'll make you happy as long as you live. I promise. So—"
Her kiss cut his words short. It was a deep kiss, their tongues intertwining as they exchanged saliva. She finished by clinging to his lower lip, and their lips parted, trailing threads of saliva.
"I know. I, Amanomiya Koyoi, will be your wife. I'll stay with you as long as I live."
Entranced, Koyoi once again pressed her lips onto Elt's — her beloved husband's.

Koyoi surveyed the scenery spread out below her and let out a contented sigh. Pink and purple air hung over Lescatié. Nights in the monster realm were brighter than in Zipangu. Mana dimly illuminated the surroundings so that darkness never obscured the view.
She strained her ears. The area was quiet, and couples' whispered intimacies were faintly audible. Before, when the Order army, stubbornly clinging to reason, had mounted a guerrilla campaign in the region, the air had been full of the sounds of their battles with the monster army. Recently, however, the clangor had subsided. She could really feel that the place was on its way to becoming a full monster realm.
She was in a watchtower at the very top of the castle. Her hair fluttered slightly in the distinctive warm breeze of a monster realm. She liked the view from this spot. The sight of the ongoing resistance failing and falling to the monsters reminded her of her past self.
"I never even knew this place existed," a man's voiced sounded from behind Koyoi. It was Elt, who was watching the monster city of Lescatié with her as she sat on his lap.
"Really? You know this city far better than I do," she responded, brushing her cheek against his neck with a spellbound expression.
"I always dreamed of living in this castle. It was so dazzling I couldn't get a good look at it."
Koyoi twisted her body around to face Elt.
"And now you're the king of Lescatié..." She purred, rubbing the tip of her nose against Elt's breast.
It was Druella who had made Koyoi a monster, and Druella's taste thoroughly colored Koyoi's appearance. The red and white of her kimono had given way to black and purple, and its neckline exposed the upper half of her unrestricted breasts. The bare skin of her chest and arms was inscribed with dark violet designs. The designs on her arms had originally been runes of binding, which Druella had put there to corrupt her. With Druella's guidance, however, Koyoi had overwritten them into runes of pleasure.
"Well, they call me that, but Lady Druella does all the actual ruling," he laughed bashfully.
After turning Koyoi, Druella had launched into a national administration worthy of a daughter of the Overlord. She had instructed the people in the growing of prisoner fruit and other sparsely-tended monster realm flora; she had distributed pamphlets introducing various positions and tools for getting the most out of one's daily sex life to every home; and, of course, she had commanded a monster army to ensnare the guerrilla Order forces in hiding throughout the country.
To be honest, until she had actually seen Druella govern, Koyoi had thought her just another undisciplined, sex-crazed monster. In the massive operation to capture the guerrillas, however, Koyoi had seen her observing enemy movements and flexibly issuing instructions, and repented. She now respected, and feared, Druella from the bottom of her heart.
I could never have beaten her, no matter how hard I tried.
